Key Benefits of PCA SKIN Hydrating Serum

 
These are the key benefits you can expect from using PCA SKIN Hydrating Serum:
 

🔵 Lightweight Purely Humectant Moisturizing, Ideal for Oily Skin

According to CreamScan analysis, PCA SKIN Hydrating Serum is quite moisturizing, with a moisturizing rating of 5.0 out of 10.

Is it more humectant or occlusive? It is purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a maximum humectancy of 10 out of 10, primarily due to the high content of Glycerin (est. ≈6.0%), Sodium PCA (est. ≈2.4%) and Aloe Barbadensis Leaf Juice (est. ≈2.0%).

This humectant-rich product, when used alone as a moisturizer, is ideal for oily skin, providing significant hydration in a lightweight, fast-absorbing formula without any occlusive ingredients.

❗️ Certain studies suggest that humectants alone may not effectively moisturize the skin. If you use this product as your only moisturizer, we recommend following it with one that contains at least some occlusive ingredients.

💧 A Humectant Boost for Any Skincare Routine

But it’s not limited to oily skin - such a humectant boost will also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer. This type of formulation is typically used in serums, where a light, fast-absorbing texture is key.

Please refer to the Ratings section below for details of the moisturizing rating calculation.

🟣 Slight Anti-Wrinkle Efficacy

According to CreamScan analysis, PCA SKIN Hydrating Serum has a slight anti-wrinkle rating of 0.4 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Niacinamide (est. ≈0.3%),
 one of the most effective and well-researched anti-wrinkle ingredients. A clinical study involving 30 participants (Kawada et al.) confirmed that a cream with 4% niacinamide reduced the average depth of wrinkles around the eyes by 9% after 8 weeks of use, compared to a vehicle (the same formulation without niacinamide).
 
Among others, PCA SKIN Hydrating Serum also contains Gluconolactone, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Gluconolactone provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards.
 
While this does not categorically rule out the possibility that Gluconolactone may reduce wrinkles, its efficacy is not supported by convincing, vehicle-controlled, double-blind clinical studies - at least none that were available to the CreamScan team at the time of publication.
 
Therefore, this ingredient does not contribute to the anti-wrinkle rating.
 
📌 Moisturizers, when used regularly, are proven to prevent wrinkle formation and even reduce existing wrinkles. Therefore, this product, like any other moisturizer, can deliver some additional anti-wrinkle effects through its moisturizing action.
 

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.

🍀 Rich in Skin-Protecting Antioxidants

We estimate that PCA SKIN Hydrating Serum is rich (> 3%) in antioxidants, specifically Aloe Barbadensis Leaf Juice (est. ≈2.0%).

A key benefit of antioxidants is their ability to reduce oxidative stress caused by free radicals and therefore prevent accelerated skin aging. Studies also show that antioxidants can protect against environmental damage such as UV radiation and pollution, and help reduce inflammation and skin redness.

📌 Please note that this is not a complete list of benefits. We are in the process of enhancing our AI model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.

Things to Be Aware Of: PCA SKIN Hydrating Serum

 
CreamScan AI identified a few things to consider before adding PCA SKIN Hydrating Serum to your skincare routine:
 

⚠️ If It’s Your Only Moisturizer, It Needs to Be Paired with Some Occlusives

While humectants are highly effective at attracting water to the skin, studies (J. N. Kraft, C. W. Lynde) suggest they may not be efficient when used alone.

One major drawback of purely humectant moisturization is that the water attracted by humectants to the upper layers of the skin can evaporate completely into the environment through transepidermal water loss (TEWL). Adding occlusive ingredients helps seal this moisture into the skin and prevent further water loss.

If you’re using PCA SKIN Hydrating Serum as your only moisturizer, consider pairing it with one that contains at least some occlusive ingredients, such as oils, butters, or silicones. These work alongside humectants to create a protective barrier, locking in hydration and ensuring longer-lasting moisturization. The amount of occlusive needed depends on your skin type - the drier the skin, the more occlusives it requires.

If this product is used not as a standalone moisturizer but as part of your skincare routine, such as a toner or serum, it should be applied before your main moisturizer (unless it's a sunscreen), which will provide the necessary occlusivity on top of it.

Pros & Cons of PCA SKIN Hydrating Serum

 
Here’s an overview of the pros and cons of PCA SKIN Hydrating Serum to help you decide if it’s the right choice for your skincare routine:
 

🟩 Pros:

✅ When used alone: Provides humectant-rich moisturizing ideal for oily skin
✅ As part of a routine: A humectant moisturizing boost, beneficial for any skin type
✅ Lightweight texture
Provides slight anti-wrinkle efficacy
✅ Rich in antioxidants that combat oxidative stress associated with accelerated skin aging and defend against environmental damage
 

⭕ Cons: 

⚠️ Only if used as a standalone moisturizer - it needs to be paired with occlusives to seal in humectants
   

Summary: PCA SKIN Hydrating Serum

 
Based on the ingredient list analysis, CreamScan AI suggests that PCA SKIN Hydrating Serum
, when used alone, delivers lightweight, humectant-rich moisturizing, making it ideal for oily skin. As part of a moisturizing routine, it provides a humectant boost, beneficial for all skin types.
 
PCA SKIN Hydrating Serum contains ingredients with proven evidence of anti-wrinkle efficacy that may offer a slight anti-wrinkle effect. As a result, you can expect a positive, though relatively minimal, impact on wrinkles.
 
 
With its high antioxidant content, PCA SKIN Hydrating Serum helps protect against free radical damage and offers multiple benefits for all skin types, including preventing premature aging, defending against environmental damage, and calming inflammation.
 
That said, there are some things about PCA SKIN Hydrating Serum worth noting.
 
Looking at its moisturizing profile, we found that it doesn’t contain any occlusive ingredients, potentially allowing the moisture attracted to the skin by humectants to evaporate. Therefore, if it’s used as the only moisturizer in a routine, it’s recommended to pair it with one that contains at least some occlusive ingredients, such as oils, butters, or silicones.
